Other claims from this paper (14)
- Intervention effect Validamycin A produced a five-fold increase in trehalose level in Lotus japonicus during salt treatment.
- Intervention effect Validamycin A treatment enhanced biomass by 20% in salinized Lotus japonicus plants.
- Intervention effect Saline conditions decreased shoot and total plant dry weight of Lotus japonicus by 40%.
- Intervention effect Under saline conditions, the decrease in shoot and total plant dry weight of Lotus japonicus was only 15–20% in plants treated without or with validamycin A.
- Observation Lotus japonicus might be considered a salt-sensitive legume.
- Intervention effect Salt stress inhibited nitrogenase activity of Lotus japonicus by almost 40%.
- Intervention effect Validamycin A had no effect on nitrogenase activity of Lotus japonicus.
- Intervention effect Saline conditions inhibited the activity of sucrose synthase in Lotus japonicus nodules.
- Intervention effect Saline conditions inhibited the activity of alkaline invertase in Lotus japonicus nodules.
- Intervention effect Saline conditions inhibited the activity of trehalose-phosphate synthetase in Lotus japonicus nodules.
- Intervention effect Validamycin A treatment decreased the activity of sucrose synthase in Lotus japonicus nodules.
- Intervention effect Validamycin A treatment decreased the activity of trehalose-phosphate phosphatase in Lotus japonicus nodules.
- Intervention effect Validamycin A treatment decreased the activity of trehalase in Lotus japonicus nodules.
- Mechanism The results support a possible role of trehalose as an osmoprotectant under salt stress in Lotus japonicus.
